The driver of a tractor-trailer suffered minor injuries after his vehicle flipped in the middle of the night.
Around 12:30 a.m. the driver lost control and rolled the truck, near the intersection of Highway 440 west and the 13 south.
Emergency crews needed five hours to clean up the mess of wood and construction supplies.
Around 5:40 a.m. Tuesday the highway was reopened to traffic.
Police are looking at possible causes including faulty brakes, cold temperatures, or simply the driver going too fast.
